Now byrotating the crankwheel 22 the tool or pencil at the end of the bar willcut or draw a curved line, and if it be desired to cut parallel curvedlines by operating the ratchet-lever 18 this may be accomplished.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages ofthe invention will be readily understood without requiring furtherexplanation.

The device is exceedingly simple in construction, strong in parts, andmay be placed upon the market at comparatively small cost.

'While I have shown and described the preferred embodiment ofmyinvention, I would have it distinctly understood that I contemplateand reserve to myself the right to make such changes as fall within thescope of my claims.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In an instrument of the character described, the combination with thetrack, of a carriage mounted to reciprocate thereon, a beam having asliding engagement in said carriage, means for sliding said beamlengthwise, said beam being provided with a head, and a tool-barrotatably connected with said head, and provided with means for lockingit, substantially as set forth.

2. In an instrument of the character described, the combination with thetrack, of a carriage mounted to reciprocate thereon, a

beam having a sliding engagement in said carriage, a ratchet-wheelcarried by said carriage and provided with a screw-shaft, a nut engagedwith said screw-shaft and adj ustably connected with said beam, saidbeam provided with means for clamping and holding a tool or pencil,substantially as set forth.

3. In an instrument of the character de- 4:. In a tool of the characterdescribed, thev combination with the standard, a post journaled therein,a pulley journaled on said post, a track connected to said post andprovided .at its outer end with a foot having means for fastening itstationary, a carriage adapted to slide on said track, acord orconnection wound about said pulley and having one end secured to thecarriage at one point and the other end passing around a sheavejournaled to the outer end of the track and secured to the carriage atanother point, and a beam having a head at one end, means forlongitudinally adjusting the beam, and atool or pencil bar rotatablyconnected with said head and provided with means for fixing the tool-barto said head, substantially as set forth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
